2014 Chevrolet Sonic

A new EverStart Maxx lead-acid battery (Group Size H5/47, 12V, 650 CCA) was bought at Walmart on 07/14/2026 and installed the same day in a 2014 Chevrolet Sonic. It was installed correctly: correct polarity, both terminals tight and free of corrosion, hold-down secured. The car ran normally for about eight weeks, with no warning lights or electrical symptoms. On 09/10/2026 at about 12:00 p.m., the car caught fire while parked. It had not been driven or started since about 5:00 p.m. the day before (about 19 hours), so the engine and charging system were off. The fire appears to have started at the battery. It stayed in the engine compartment but melted the underhood fuse box and the engine wiring harness. The local volunteer fire department responded, and a police report was filed. No one was hurt, but a battery fire in a parked, unattended car could easily spread to a home, garage, or other vehicles. The car had an earlier front-end repair after hitting a deer. It had been driven for more than a year since that repair with no electrical problems. The vehicle and the battery remains have been left in place and are available for inspection. The retailer and manufacturer have not inspected them yet.

Around April of 2025, I noticed loud engine noises and cold start loud noises coming from the engine. My car has been in the shop multiple times since then and I opened a case with GM about multiple repair issues with my 2014 Chevy Sonic LT even though I take excellent care of the vehicle and perform all maintenance on the vehicle, and now this loud engine noise issue and leaking oil. I was driving home from a relative's home Saturday night Dec 27th late evening on the expressway when I noticed my car driving very sluggish and jerking and make extremely loud engine noises and continued burning oil smell in the cabin of the vehicle. No check engine light or oil light, now I had stopped by the service department earlier in the week when and oil pressure light came on, and they stated no issues. I made it home without incident, but the car was not running right. The car was brought to the dealership service department Monday Dec 29th, and they informed me they found broken plastic pieces of guard rails that secure the timing chains in the engine which may have caused serious damage to the engine. The dealership wanted 4k dollars to repair it after they could not properly diagnose a known online issue that I found out a lot of these Chevy drivers have found out about and having me repair other items on the car instead of fixing the leaking oil problem and whatever was going on in the engine. The manufacturer has not inspected this issue now only the service department at the local Chevy dealership has, however I had a case open with GM before this final incident occurred on Nov 1st after my last repair and complaint to the dealership about loud engine noises. GM would not take my concerns seriously and stated we are sorry, but your car is out of warranty even though this is a known issue of this plastic guard rail failing and other serious engine issues with Chevy. I would like the NHTSA to be involved in this matter and investigate this matter if possible.

The contact owns a 2014 Chevrolet Sonic. The contact stated that while driving at various speeds, the A/C failed to function as intended. The contact stated that there was hot air blowing from the vents at all time. In addition, the contact stated there was an abnormal sound coming from the engine, with an abnormal fuel burning odor on the interior and exterior of the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic; however, no cause for the failure was found. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 14V417000 (EQUIPMENT). The failure mileage was unknown. The VIN was not available.

Factory Radio. It will turn on and there is sound, but the screen is frozen. You can see everything on the screen, but if you press something on there it doesn’t do anything. Also, you can’t control it from the steering wheel either. I already removed the battery cables for 30 minutes and that didn’t correct the issue. It’s my opinion that the radio needs a software update. I have seen where other Chevy Sonic models and different years have had this exact issue with the radio, because you recalled and fixed them. This issue needs to be corrected.

Vehicle keeps throwing error code P2138 there is a current known issue that GM is aware of see notice 070604019F. Water gets in the electrical connections of sensors and is an issue as it causes check engine light and can decrease power of the acceleration of the vehicle which is a safety hazard. My vehicle has been with the dealer now for a third time for same issue. They’ve had it for 3 weeks and 2 days total. Still an issue.

The pretensioner cable that secures the end of the seatbelt to the seat frame had severed. I am told the pretensioner has a small explosive inside its barrel that I assume releases some sort of spring internally upon impact of a collision. The release of this spring is supposed to pull the pretensioner cable downwards and by extension pull the seatbelt end tighter. This in conjunction with the seatbelt retractor would then keep the driver or passenger tight to the seat in the event of an accident. I notice the cable for the driver side pretensioner over the last few months had strands of steel breaking until it had finally completely severed. I have kept both halves of the severed cable if inspection is requested. This is an extremely unsafe situation to occur. Had I gotten into an accident with the cable partially or completely broken it would have rendered the seatbelt essentially useless. There were no warning lights or associated codes ever displayed from the vehicle’s computer. There were no inspections done by insurance, police, manufacturer, dealership or any others. I ended up ordering the part online to fix myself. I used all manufacturers torque specs and procedures to replace. I fixed it myself because it was my daily driver vehicle and I needed to have it working safely as soon as possible. When I noticed the cable had completely broken I drove my vehicle home and did not drive it again until I had the new part and it was replaced which was about two weeks later. I had asked the dealer and searched for recalls for my vehicle and neither the dealer nor the nhtsa recall search showed anything regarding issues with the pretensioner cable. I did end up seeing GM had issued a recall for a similar pretensioner cable (about 2500 vehicles) for a few of their full sized trucks and SUVs. The claim was based on where the cable was in the vehicle it had abnormal amounts of metal fatigue from drivers exiting and entering. I believe the same issue happened to me.

"off" remains illuminated on my passenger airbag light whether or not someone is sitting in the passenger seat. It's actually somewhat rare to see "on" illuminated. There was a recall on this model for airbag issues but my vehicle specifically was not recalled. My vehicle was recalled for catalytic converter but I'm still getting codes. Most of the problems the Sonic has been recalled for, my vehicle has symptoms of but I get cannot afford to pay repair cost up front and I cannot find a mechanic who would be willing to take the steps to report my vehicle should've been apart of the recall.
